PENNSYLVANIA — Vishay Intertechnology, Inc. launched new low-profile, high-capacitance solid tantalum chip
capacitors —packaged in a compact P case size — designed to provide superior reliability while making room for
greater functionality in compact electronics.
Part of the Vishay Sprague TANTAMOUNT® product line, the new
capacitors in the 527D series are designed for input/output buffering, dc-to-dc conversion, and noise suppression
applications in PDAs, cell phones, LCD display drives, and other handheld and portable appliances.
capacitors feature a low-profile P case size with single-sided lead (Pb)-free terminations that enable direct
placement under grounding shield applications. The unique uniform geometry of each 527D device aids in accurate
placement and more reliable performance.
The capacitors' small dimensions, which measure 0.087 in. by
0.049 in. by 0.039 in. [2.2 mm by 1.25 mm by 1.0 mm], also allow designers to conserve board real estate and add
features to lighter, smaller, and more portable electronic systems.
The capacitance ratings for the devices being released today
are 10 µF at 10 WVDC and 33 µF at 6.3 WVDC with tolerances of ±10% and ±20% (standard).
Tantalum capacitors in the 527D family are conformal-coated and are available in 8 mm and 12 mm tape-and-reel
packaging per EIA 481 1 and reeling per IEC 286 3. The new devices in the P case size are specified for an operating
temperature range of –55 °C to +85 °C, or up to +125 °C with voltage derating.
and production quantities of the new 572D capacitors are available now, with lead times of 8 to 10 weeks for larger
